Legend of the Mystical Ninja on the SNES is a half brawler/half platformer game with quirky humor and a very japanese setting and style. It's very challenging (maybe unfairly so) which can make it quite frustrating at times. Not particularly recommended outside of Goemon megafans.
As an aside, its soundtrack deserves a shoutout for being incredible and super underappreciated.
